@FBM,
But you are defining what "willful stupidity" is. And "shoved". And "mercilessly".
What's your objection to the page of the book hh posted? It served as a warning about people who use the word "electricity" as if they know what it is and pose as being scientific when they are not. There are many people who use expressions such as "quantum theory" or "physotomous" dropped casually in conversation, as if they are so simple they need no explanation, taking advantage of the listener not wishing to seem stupid by asking what they mean as they would be if the thing was simple.
If you ever read Nick Leeson's book Rogue Trader you will see that technique employed to break a high status bank. And deliberately. There are people running around not far from here who use certain buzzy scientific expressions to bolster their intellectual credentials and they don't know their arse from their elbow. Leeson's superiors, a lady particularly, couldn't admit that they didn't understand his memo appealing for another large tranche of dough. To admit that would be mortifying for a superior. Especially a lady. So he got the extended credit he had asked for in order to bet his way out of trouble.
After all, a buzzy scientific expression is only buzzy because nobody knows what it means. If everybody knows what it means it has no buzz. It is common in that case and thus no cachet adheres to it.
The young lady in the picture is using the dryer to help make herself look pretty and not worry about how the process is effected. Just as we all do many times a day when we switch lights on and adjust thermostats in greenhouse heaters without it ever entering our heads what electricity is.
The ladies of our evolution washed the clothes on the rocks beside the river without a thought for how the rock was formed or where the water was coming from. Such ideas are inimical to gossiping and women gossiping is a force to be reckoned with. So one can easily see that men, or some men, might try to reduce women gossiping by having them focus their minds on more serious issues.
As an exercise in how to choose a photograph to match the text on the page, whilst remaining within the bounds of Christian decency, it was most excellent.
I don't see your objection and a series of assertions, no matter how long, does not support it.
